Abstract
A permeator system for separating at least one gaseous component from a feed gas mixture containing at least one other component using a semi-permeable membrane is disclosed which maintains high permeate product purity and desired component recovery during periods of turn-down in capacity. In accordance with the present invention, the permeator system contains a series of flow and pressure sensors and valves which regulate differential pressure across the membrane based upon permeate product demand or feed availability.
